MACHINE FOR THE MANUFACTURE'OF BUTTONS, 84C.

SPECIFICATION forming part of Letters Patent No. 226,696, dated April20, 1880,

Application filed January 13, 1880.

To all whom it may concern Be it known that I, JEAN FELIX BAPTE- RossEs,a citizen of the Republic of France, and a resident of Paris, France,have invented certain new and useful Improvements in Machines for MakingButtons and Similar Objects, of which the following is a specification.

The object of my invention is to construct a machine for pressingbuttons and similar objects of plastic material rapidly and under anydesired pressure, and this object I obtain by combining with the pistonof a hydraulic cylinder and its regulating cocks button-formin gdevices, as morefully described hereinafter.

In the accompanying drawings, Figure 1, Sheet 1, is a side view of myimproved buttonmachine. Fig.2,Shee-t 2,a sectional plan; Fig. 3, avertical section of part of the press; and Figs. 4, 5, and 6, sectionalviews of the cooks for supplying the fluid to the hydraulic cylinder.

On the frame X of the machine are mounted the vertical standards X,supporting the hydraulic cylinder A, the body of which is suffi--ciently strong to withstand great pressures. To this cylinder is adapteda piston, B, having the usual rod 0 passing through a stufiing-box inthe end of the cylinder. The joints around the cylinder-head, piston,and stuffing-box are rendered water-tight by means offianged strips D,of leather, rubber, or other suitable packing material, the pressure ofthe liquid insurin g the tightness of the joint.

To the lower end of the piston-rod is secured an extension of thepresser-plate G of the button-forming devices Y, which maybe ofthecharacter described in the Letters Patent granted to me August 12,1873, No. 141,749.

As shown in Fig. 3, the piston-rod has a longitudinal opening at itslower end and a transverse slot at right angles thereto. In this openingis a bar, F, having a rack at its upper part and carrying at its lowerend the plate which carries the pins for piercing the holes in thebuttons, as described in my abovementioned patent. This bar F issupported between an anti-friction roller, e, in the slot above referredto and the toothed end of a hand-lever, H, pivoted to the piston-rod atI,

also in said slot. By acting on this lever the pin-carrying plate may beraised or lowered.

The space in the cylinder above the piston and that below the piston maybe made to communicate with either awater-reservoir at a medium pressureor an accumulator at a high pressure through pipes P P, provided withcocks K L and pipes M and N.

Suppose the piston B to be at the top of its stroke and the cooks K andL to be in the positions indicated by full lines in Figs. 4 and 5, thewater from the reservoir entering through the pipe M descends into thepipe N through the cock L, and thence through the cock K and pipe P tothe space above the piston. The liquid below the piston can flow outthrough the pipe P and escape-pipe Q. The piston B descends under thispressure and carries with it the presser-plate, which imparts to theceramic objects a in'eliminary pressure. The operator then acting on thelever H depresses the pin-plate and turns the cock K to the positionshown by dotted lines in Fig. 5. WVith the cooks in these positions thespace above the piston is in communication with the accumulatorthroughthe tubes R and P and the space below the piston with the escapeoutlet Q, as before. The piston continuing to descend under theincreased pressure, the buttons will be compressed to the requireddegree. The cock K being then turned to its original position and thecock L turned to the position shown by dotted lines in Fig. 4, the spacebelow the piston is put in communication with the reservoir and thespace above the piston in communication with the outlet Q, so that thepiston will be raised to its original position and the pressed objectscan be removed from the press'to the baking-oven.

Thus by simply manipulating suitable cocks I am enabled to impart to thebuttons or other objects a gradual pressure, which can be increased toalmost any extent, so that the objects which by this means are compactlypressed do not contract in the subsequent 5 baking operation, andconsequently are not apt to get out of shape.

I claim as my invention- 1. The combination of a hydraulic cylinder,piston, presser-plate, and button-molding devices Y with pipes P P, cockL, communicating with the reservoir and outlet, the pipe N, and cock K,communicating with an accumulator, all substantially as described.

2. The combination of the piston-rod, oarrying' the 1t resser-plate Grand'having an opening at its lower end, with the rack-bar F, carryingthe pin-plate, and with the pivoted hand-lever H, having a toothed outerend gearing with said bar, all substantially as set 10 forth.

In testimony whereof Ihave signed my name to this specification in thepresence of two subscribing witnesses.
